of which thefollowing is a"specification.'

- My. invention relates tov windowscof the that the sashes thereofcan beswung inwardly from the window frameand supported in position to permitcleaning of both sides of either sash from a pointg'interiorlyw of,a-building, thereby eliminating the present practiceof cleaning windowsex teriorly'of the building, and 'the' dangers attendantsuch practice. 1j v I will describe only one form of apparatus for facllitating thecleaning of windows em-1 bodying my invention," and. i will then pointoutthe novel features thereof'inclaims;

It will bevunderstood that by firstpositioning the arm 25C and then adjusting, the plate 23 to -cause thelip 24 to engage thec-inneredge'of-th'esill 16, thebracket B can besecurely posi tionedupon the sill," g 4 I rail of-thesash; and" agripping' member 44 e membe .22., as s n igu e 2, is: provided withvertically alined sleeves 30 and 31 of angular form in cross sectionandreceiving a tube 32, of, similar shape in cross section. This tubeconstitutes a part of the standard T and thelatter also includes a rod33 angular in cross section and adjustable vertically within the, tube.32, a set.

A seeondtube 35 is supported upon. the rod 33 and is designedfor the purpose of; providing supporting means'f'or the gripping membersofthesash c1amps, as-wi1l be more-fully described hereinafter. The upperend of the rod 33' ise'pro-vided with a right angnlarly disposed arm 36having a head 37" which is ads; tedte seat within a socket 38 secured totiie upper side of thelwindow frame 15. loosening the; set screw 34- therod 33 Qan-bejadjnsted tomovethehead .37 into or ont e'i the socket 38,and: to provide manual means-i01 moving the rod a manipulating rod 39(Figure 1)} is mounted for vertical movement in-a; guide-40 formed on ithe bracketB.

Thegripping member 44' is connected toa bracket 47 throughha double-hinge- 48, and

the bracket isadjiiistable vertically upon the tube-35' and -adaptedltobe locked in. any ad justed position by-means of aset screw 49.

As clearly shown in Figure 1, the members 43 and 44 are shaped toreceive the lower and upper edge, respectively, of the-lower and;meetingv raiis of'the lower sash S, and;

pins-50i are formedwon the members for .eneas ment within sockets formedin the sash. rails-to prevcnthorizontal movement: of the members uponthe rails after-theyhave been once-applied. From this'descriptionlitwill;

After theapplication-of the gripping member it is-to be understood that the setscrew 49 is adjusted to lock the bracket 47 on the tube 35.- sothatthesash as a unit 1s firmly clamped between the members 33 and-34.-

The clamp for the upper sash S, also ineludes. a relatively stationary,supporting member 51 provided with a rod 52 of angular cross sectionslidably fitted in. a sleeve.

Afterthe cleaningof this pane has been effected,theuppersashdS can? likewise be moved inwardly. by first; 'apply ing'the gripping member 64 5tothe 'sash, l it;

being understo'od that theasuppor'ting mem- 'ber 5'1 has beenpreviously.applied,-- and then" removing the'bea'd 20, whereupon theupper.

sash can thenube swung-inwardly? toithe rightangular position shown inFigure 5-,

or to any intermediate position so that both "sides of the window paneare accessible for clean ng. if Theidou'blewhinge connections. be-

tween the-"clamps andi the :brackets allow Eof the movement ofthe sashesfrom their normal position inwardly to the right angular position, andin such manner that the movement of one sash and its supporting meansdoes not interfere with that of the other. I

sash is in position. By upward adjustment of the members 44 and 64 suchadjustment being effected through a loosening of the screws 49 and 70,the members can be moved free of the sashes .so that by slightly raisingthe latter they will be disengaged from the supporting members 43 and51. The entire apparatus can now be removed from the window by firstdisengaging the head 37 from the socket 38- and releasing the clamp Cfrom the sill 16.
